ADJUSTABLE RING LABOOK.

This invention vrelates to adjustable ring books and the like` and v'is fully described in the following specification and shown in the accompanying` drawing, in which:

Figure 1 is an end elevation of the ring book embodying the invention;

Fig. 2 is a front elevation of the back strip showing the rings therein;

Fig. 3- is a section showing the ring in open position' Fig. 4 is the same showing the ring in closed position; and

Fig. 5 is a partial section on the line 5 5 of Fig. 4.

The embodiment illustrated comprises a metal back strip whichis preferably flat and has rolled edges 11, 12, the latter being preferably round in cross-section and uniform from end to end. These edges are not completely closed but have an opening 13 which runs therethrough the length of the stri Ap U-shaped ring 14 which is preferably made from sheet metal and placed so that the cross-section of this ring is rounded near the center as shown in-Fig. 5. One end of this ring terminates in an elongated guide 15 which is curled outwardly and upwardly at 16 so as to interlock with either of the rolled ledges 11, 12 and to be freely slidable longitudinally therethrough.

The free outer end of the ring 14 is provided with a hook 17 which, when the ring is placed therein into closed position as shown in Fig. 4, snaps into the recess 13 thereby locking the ring 14 in closed position, the stiffness of the ring holding it closed and providing suiiicient friction between the ends 16 and 17 and the rolled edges 11, 12 to prevent the rings 14 being readily moved along the grooved strip 10.

Covers 18, 19 may be attached to the grooved strip 10 in any desired manner, as by means of a iieXible cloth strip 20 which may be secured to the back strip 10 by means of rivets 21 or the like.

Thus it will be seen that a convenient ring book is provided in which the rings may readily be removed therefrom or moved from one position to another on the back to accommodate sheets having different spacing of holes therein, this device is also very economical of space, the height of the rings from vthe back of the book being reduced to a minimum.

This arrangement permits. as many rings Application filed April 13, 1925. Serial Nen 22,811.

as are desired to be used at the lsame time and with' any desired. spacing `to Asuit the spacing of the holes in the sheets used. It willl also be noted that th-e rolled edges are identical on the two sides so that the U- shaped members may be used on either side or, if desired, on both sides at the same time.

lVhilo I have shown and described but a single embodiment of this invention, it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made which do not depart from the spirit and scopel of the invention as disclosed in the appended claims.

l claim:

1. lin a ring book, a metal back strip having inturned edges, and a U-shaped member adapted to have one end interlock with one of said edges and to be swung about said interlocked edge so that the other end is brought into engagement with the other edge.

2. In a ring book, a metal back strip having inwardly curved edges, and a U-shaped member adapted to hav-e one end interlock with one of said edges and to be swung about said inter-locked edge so that the other end is brought into engagement with the other edge.

3. In a ring book, a metal back strip having inturned edges, and a U-shaped member adapted to have one end intcrlocked with one of said edges at any point throughout its length and to be swung about said edge so as to bring the other end into engagement with the other edge.

4. n a ring book, a metal back strip having inturned edgcs,and a U-shaped member adapted to have one end interlock with one of said edges and to have the other end swung into engagement with the other edge, the outer end of said member being adapted to have locking engagement with said other' edge.

5. In a ring book, a metal back strip having inturned edges, and ka U-shaped member having one end widened and adapted to have sliding engagement with onev of said edges and to be swung about said edge so as to bring the other lend into engagement with the other edge.

6. In a ring book, a metal back strip hav-` ing inturned edges, and a U-shaped member adapted to have one end interlock with one of Said edges and. to have the other end.

lll)

swung into engagement with thefother edge, said U-shaped member being' stamped'lfrom sheet metal.

7. In a ring book, a metalbnck strip, having inturned edges, anda Ushapedm'e'mber having' one end adapted to have rockingeugagement with one of said edges and having means for preventing laterali swinging of said member but permitting said member to swing' into engagementl with the#l opposite:

edge,4 the outeri end? of saidi Ulshglped' mehr bei' being adapted. to ioekwith-saidopposite edge.

S. In a ring book, a sheet metal buck strip having inwardly turned edges of uniform Crosslsect'ion throughout= and u U-shuped ringmember adapted to i'rictionuli Y engage suidedges at any point in the length of Said strip.,A

In testimonyv whereof I hereunto Set my `20 hand this'vth'day of April, 1925.
